I have promised images and here they are. As Steve already has posted the comparison image I'll go straight to my own images. These are rendered with a fair amount of quality overkill. I don't have the patience to wait and see what quality setting looks best, so I just set them on continuous rendering over night. I think that is called progressive rendering in other apps. The resulting quality usually lands somewhere between 10000 and 20000. I can of cause render longer but then I start to not see the difference. These are unprocessed images straight from Fractal Architect.
